Annotation Elements

Table 2-79 describes this annotation's elements.

Usage

Use the @VirtualAccessMethods annotation to define access methods for mappings with in which accessType=VIRTUAL.

Examples

Table 2-79 shows an entity using property access.

@Entity
  @VirtualAccessMethods
  public class Customer{
 
    @Id
    private int id;
...
 
    @Transient
    private Map<String, Object> extensions;
 
    public <T> T get(String name) {
        return (T) extensions.get(name);
    }
 
    public Object set(String name, Object value) {
        return extensions.put(name, value);
    }

In addition to using the @VirtualAccessMethods annotation, you can use the <access> and <access-method> elements in your eclipselink-orm.xml file, as shown in Example 2-127.

<access>VIRTUAL</access><access-methods get-method="get" set-method="set"/>@Entity
